Why are full frame DSLR cameras preferable?

APS-C and DX sensors

APS-C and DX are sensor formats for DSLRs, DSLMs and compact cameras and, along with micro-four-thirds and full formats, are the most popular format sizes.

The name APS-C stands for Advanced Photo System Classic and was introduced by Canon in 2000 for its first DSLR. The term goes back to the APS recording format from Kodak and other manufacturers, which was introduced in 1996 as the standard for analog photography and was a third of 35mm film. Since this development took place shortly before the introduction of the digital camera, the format was initially unable to establish itself.

The APS-C format does not describe a uniform standard because it is not standardized. However, this term has established itself in forums and among photographers. Depending on the manufacturer and model, the sensors have an approximate size of 22.3 x 14.9 mm. This results in an aspect ratio of 2: 3. Nikon uses the designation DX for its sensors of the same format. Since the APS-C format is smaller than the 35mm format, photographers have to consider a crop factor of around 1.5 - for Canon 1.6.

Compared to the full format, which is often seen as state-of-the-art in photography, the APS-C format offers several advantages and disadvantages. In principle, larger sensors can absorb more light, which can lead to better images. This is particularly noticeable in poor lighting conditions. In addition to the number of pixels, the type of image sensor is therefore the decisive criterion for image quality. In comparison to APS-C, cameras in full format deliver better quality images.

Further disadvantages arise in the wide-angle range: Due to the crop factor of 1.6 (or 1.5), landscape shots are only possible to a limited extent due to the enlargement of the section, which is why full-frame cameras are to be preferred here as well.

However, cameras with APS-C sensors also offer many advantages. Cameras in APS-C format are, on the one hand, significantly cheaper and, on the other hand, a lot smaller and more manageable than full-format cameras. That is why cameras with APS-C sensors are particularly suitable for traveling. Furthermore, the disadvantages in terms of quality and angle of view can be neglected. On the one hand, the differences in quality are only marginal; on the other hand, pictures can also be taken in wide-angle format by purchasing suitable lenses.

If you are not a professional photographer, cameras with APS-C or DX format represent a good compromise between image quality and price and are ideal for casual photographers, ambitious amateur photographers and even professional photographers.
